“…' In most cases HCB is connected with burning events and metallurgical processes involving the use of chlorine (12). It could be shown that in the case of the Ebro delta in the western Mediterranean the river is a major source of HCB to the coastal environment (30). The HCB was mainly associated with the particulate phase.…”

“…Pollutants originating from this site are also known to be transported downstream, mainly mobilised during floods (Grimalt et al unpublished data), ending up in the Ebro delta, 90 km away from the reservoir (Grimalt et al 1988;Amaral et al 1996;Quirós et al 2008).…”

Despite many efforts for pollution abatement in aquatic ecosystems, there are still some cases of high accumulation of industrial pollutants due to past activities. In Flix reservoir (Ebro River, Spain), there are around 200,000-360,000 tons of industrial pollutants with a high concentration of heavy metals and organochlorides due to the activity of an organochlorine industry during more than half a century. This exceptional amount of pollutants provides a good opportunity (and need) to analyse their effects on fish populations under natural conditions, which is rarely available to ecotoxicologists. We compared the reproductive traits and prevalence of diseases and parasites at this impacted area with a neighbouring upstream reservoir unaffected by the pollution (reference sites) and also to downstream sites. Deformity, eroded fin, lesion and tumour (DELT) anomalies and ectoparasites were clearly more frequent at the impacted area for several fish species (common carp, roach and pumpkinseed). A significant negative impact of Flix reservoir on condition (eviscerated and liver weights, adjusted for fish size with analysis of covariance) and reproductive traits (gonadal weight and number of mature eggs, adjusted for fish size) was also detected for several fish species. The responses to the pollutants were species-specific, and common carp (Cyprinus carpio) was the species with the clearest effects on fitness-related traits at the impacted area, despite also being among the most tolerant to pollution.

“…Measurable amounts of HCB were also found in all samples (Table 2), with levels along the Spanish coast being slightly higher than those along the French coast. This is probably related to the existence of an industrial source in the vicinity of Stn 1, upstream of the Ebro River (Grimalt et al 1988). …”

Muscle concentrations of organochlorinated compounds as well as biliary levels of polycyclic aromatic hydrocarbon (PAH) metabolites were determined in red mullet Mullus barbatus as a sentinel species for assessing the pollution along the western Mediterranean coast. A battery of biochemical markers -biotransformation and antioxidant enzymes -were also measured in liver subcellular fractions to assess exposure to pollutants. Among them, 7-ethoxyresorufin O-deethylase (EROD) activity, as well as 7-penthoxyresorufin O-deethylase (PROD) activity and cytochrome P450 1A (CYP1A) content evidenced strong differences among sampling sites, and a good correlation with the amount of PCBs bioaccumulated by fish. No clear pollution-related response was observed for cytosolic glutathione S-transferase, whereas uridine-diphosphate UDP-glucuronyltransferase (UDPGT) was elevated in fish from polluted sites. Antioxidant enzymes -superoxide dismutase (SOD), catalase and glutathione peroxidase (GPX) -were used to assess oxidative stress. Among them, catalase activity was well related to PCB body burden.
